Issue #8970 has been updated by sawa (Tsuyoshi Sawada).
akr, The difference between `Array#transpose` and `Array.zip` is just the same as with `Array#transpose` and `Array#zip`. That is, when any non-first array is shorter than the first, it is complemented with `nil`.

Feature #8970: Array.zip and Array.product

Most of the time when I use `Array#zip` or `Array#product`, I feel cumbursome that I have to take out the first array and pass it as a receiver. For example, if I have
a = [[:a, :b, :c], [:d, :e, :f], [:g, :h, :i]]
I have to do something like this:
a.first.zip(*a.drop(1)){...}
a.first.product(*a.drop(1)){...}
Sometimes, the receiver (i.e., the first array) has significance, but most other times, that breaks asymmetry, making the code look ugly.
I would be happy if we had `Array.zip` and `Array.product` in addition so that we can do it like this:
Array.zip(*a){...}
Array.product(*a){...}
